I´m adding multiple dropdowns via component factory by clicking a button. Every time i add a new dropdown, it appears on top of the previous one, which is a problem, because i need it below. Is there a way to set the position of the new component in relation to other components of the same type?
#ViewChild('additionalDropdown', { read: ViewContainerRef })
private additionalDropdown: any;
...
let componentFactory = this.resolver.resolveComponentFactory(MultiselectComponent);
let componentRef = this.additionalDropdown.createComponent(componentFactory, 0, this.additionalDropdown.injector)
Template:
<ng-container #additionalDropdown></ng-container>
The inserted component's position is the second argument to createComponent().
You're doing createComponent(componentFactory, 0) so you're always inserting the component as the FIRST view in the container (zero = first position).
If you passed no value for the second argument, the component would be inserted as the LAST view, but you can't do that since you want to pass 3 arguments.
You could try to pass null as the second argument, but I'm not sure it will work:
this.additionalDropdown.createComponent(componentFactory, null, this.additionalDropdown.injector);
Or you could have a manual counter (this would work for sure):
const counter = 0;
this.additionalDropdown.createComponent(componentFactory, counter++, this.additionalDropdown.injector);

I want to style a grid row after clicking on it. I get the grid row / item in the itemClickListener, but I need to avoid using grid.select(item). I have achieved the desired output which would highlight the row I clicked on with the grid select method, but this causes problems for my app since I do not want that row to be selected, but I want it to be just highlighted, e.g. apply a CSS style to said row. This is my code so far:
grid.addItemClickListener(e -> {
grid.deselectAll();
grid.select(e.getItem());
});
as well as:
grid.setStyleGenerator(row -> grid.getSelectedItems().contains(row)
? getRowSelectedStyle(row)
: null);
I cannot seem to find anything on the forums which could apply a style name for the clicked row.
You probably need to add a property to your item Bean, se "clicked".
Then you could do
grid.addItemClickListener(e -> {
e.getItem().setClicked(true);
grid.getDataProvider().refreshItem(e.getItem());
});
And
grid.setStyleGenerator(row -> row.isClicked()
? getRowSelectedStyle(row)
: null);
This is the code I've found to retrieve the correct draggable element and edit it's dimensions, during the onBeforeCapture() responder. Changing dimensions during this responder is in accordance with the documentation. This seems to work in only changing the dimensions, the other problems is that I am using the renderClone method, and so the draggable is just dragging with a huge offset that is not close to the correct mouse position. Also dnd is treating the drop placeholder as if the draggable is the original large size. Is there any way to correct for this mouse position, and placeholder dimensions? I've looked into adding mouseDown/mouseUp handlers on the inner element of the draggable but that doesn't seem to work either.
const cardSize = 140;
const draggableAttr = "data-rbd-drag-handle-draggable-id";
const getAttr = (key: string, value: string) => `[${key}=${value}]`;
const draggableQuery = getAttr(draggableAttr, update.draggableId);
const draggable = document.querySelector(draggableQuery);
draggable.setAttribute("style", `width: ${cardSize}px; height: ${cardSize}px;`);
I noticed onBeforeCapture was triggering after onDragEnd (therefore resizing the draggable improperly), so I created some state to remember the last beforeCaptureResult and return if it is equivalent to the current result.
i would like to have one list select that will have more than one style, i put two kinds of object's one is a group of users (bold), rest are users (italic or regular) is it possible to add style that will be added to part of added obj?
My code looks like this:
for(Usr usr: userSearchResult){
listSelect.addItem(usr);
}
listSelect.addStyleName("bold");
for (Gr gr : groupSearchResult) {
searchList.addItem(gr);
}
and also have style set in css correct similar to this
.v-select-bold .v-select-select {
font-weight:bold;}
i would be glad to solve this by myself but that was two days ago now i'm in a dot ;)
Thanks in advance for help!
You can store your row as a label with style. In the container there will be a label instance. There you can simply add the style.
Container container = new IndexedContainer();
container.addContainerProperty(NAME_PROPERTY, Label.class , "");
for (int i = 0; i <= 50 ; i++) {
Item item = container.addItem(i);
Label label = new Label(HashUtils.getRandomSalt());
label.addStyleName(style)
item.getItemProperty(NAME_PROPERTY).setValue();
}
return container;
You can't style rows of a ListSelect. You can use a Table component with one column to achieve a similar result. Table.setCellStyleGenerator method is used for differentiating styles for each cell (each row in your case).
I am new to DoJo development so this could be basic.
I have created an EnhancedDatagrid and it shows the data fine.
The data comes from an JSON store in a different page.
I have a button which causes that one new entry is created in the datastore and then my datagrid is 'refreshed'. This works fine.
But now i want only as the last step to change the style of the first row in my datagrid.
(I need to make the newly added row more visible.)
But i simply can't figure out how to get a handle on the first row in a datagrid.
...
grid = new dojox.grid.EnhancedGrid({
id: strId,
store: store,
structure: layout,
}, document.createElement('div'));
dojo.byId(placeHolder).appendChild(grid.domNode);
grid.startup();
var row = grid.getItem(0); // ---get the first row. How ? And how to apply new style ?
...
Thank you in advance.
Solved the problem like this:
dojo.connect(grid, 'onStyleRow', this, function (row) {
var item = grid.getItem(row.index);
if (row.index == 0) {
row.customClasses = "highlightRow";
row.customStyles += 'background-color:#FFB93F;';
}
});
I use the 'Claro' theme and it prevented me to set the background color of the row-cells.
The solution was to set the customClasses to a style like this:
.highlightRow tr
{
background-color: #FF6A00 !important;
}
Found part of the solution here: http://dojo-toolkit.33424.n3.nabble.com/row-customStyles-was-overwrite-by-claro-theme-td3763079.html
In my flex app I store the widths and visiblility of columns in an xml file. When the app loads it reads from the xml file and sets he columns values as applicable:
for(i = 0; i < columnsOrder.length; i++){
newOrder[i] = myDG.columns[Number(columnsOrder[i]) - 1];
newOrder[i].visible = (Number(columnsVisiblity[i]) == 1);
newOrder[i].width = Number(columnsWidth[i]);
}
myDG.columns = newOrder;
myDG.invalidateList();
The problem appears to be setting the visibility (it sets the visible field correctly but messes up the width)... I've tried setting it after setting the width (outside of the loop) and before the loop as well. It resizes the columns properly if I don't do anything with the visibility.
Any ideas?
Add an import statement at the top of your class file:
import mx.core.mx_internal;
Then remove using the mx_internal namespace, remove the owner of the column, change the width and then reasign the parent:
public static function resizeColumn(col:DataGridColumn, size:int):void
{
var owner:* = col.mx_internal::owner
col.mx_internal::owner = null;
col.width = size;
col.mx_internal::owner = owner;
}
This ought to do the trick (well, it did for us after a couple of days of swearing)
Is you horizontalScrollPolicy set to false on the datagrid?
"If the DataGrid's horizontalScrollPolicy property is false, all visible columns must fit in the displayable area, and the DataGrid will not always honor the width of the columns if the total width of the columns is too small or too large for the displayable area."
http://livedocs.adobe.com/flex/3/langref/mx/controls/dataGridClasses/DataGridColumn.html#width
I was able to get it to work by calling the above loop in a function twice... the first time it add the visible columns, the second time it sets the correct width. Not the best solution but I cannot spend any more time on it.
